Has anyone used Freeze 12 or Hot Shot. If so what kind of results have you had? These products are suppose to cool better than R12 or R134.

 

I use R-406 in my 88 F-150 with no problems. The evaporator temperature is a bit cooler than R-12 and the pressures are close to the same as R-12. No oil change or fldush is necessaryt as R-406 is compatabile with mineral based oil. It is available from www.autofrost.com. I also use it in my 90 Crown Vic with no problems. If you have leaks it is not a good idea to use it because it is an aztrophic mixture.
